SPEGIFIQATION forming part of Letters Patent No. 533,000, dated January22, 1895.

Application filed Jul 24, 1894. Serial No. 518,444. (No model.) atentedi ng a d ecembe 1 89 24,267m11d in Belgium July 18, 1894,11'0- 111,050-

To all whom it may concern:

Be it known that I, THOMAS LEWIS BANKS, a citizen of England, residingat Lindores, 3 Branstone Road, Kew Gardens, London, in the county ofSurrey, England, have invented a certain new and useful ImprovedManufacture of Metallic Lathing for the Ceilings and Walls of Buildings,(for which I have obtained Letters Patent in Great Britain, datedDecember 16, 1893, No. 24,267, and in Belgium, dated July 18, 1894, No.111,050,) of which the following is a specification.

My invention relates to an improved manufacture of metallic lathin g forthe ceilings and walls of buildings, more particularly in relation tofireproof construction, which shall afford an effectual key to plasteror cement no matter in what position the lathing be placed, whetherhorizontally, vertically or inclined, while at the same time themanufacture is inexpensive, the amount of metal employed for afiording agiven strength is a minimum, the metal when plastered being embedded andthus protected from the flames both on the inner and outer surfaces, andthe lathing is capable of being readily bent and produced in anydimensions both as to length and width.

According to myinventionI construct such lathing of helically coiledstrips of metal or fiat metal wires, such strips or wires beinginterlaced or woven in any desired manner for forming network withrectangular, diamond, or other shaped meshes, the coiling of the stripsbeing such as to afford an effectual key to the plaster or cement oneach side of each of the meshes, in addition to which interstices areformed at the crossing;- points of the strips which afford an additionalkey.

Figure l of the accompanying drawings shows a construction in which themetal strips or flat wires A are formed with two complete helical coilsto each mesh, formed by thecrpssing'of the strips. Thus when the plasteror cement is laid upon such lathing it will be at forded a perfect keyby reason of its pene tration into the hollow spaces formed by thecoils. 7

- The twists may be widened outat intervals at a a for enabling theinterweaving of the strips to be effected without causing labor inbending.

Fig. 2 shows a form of coiled strip constructed by a number of roundwires placed side by side.

I claim as my invention-- Metallic lathing for ceilings and wallsconstructed of interlaced coiled metal strips, the coils forming hollowspaces into which the plaster on each side of each mesh may pene trate,substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 12th day of July, A. D.1894.
